RICHARD PALMER, OF TEANEOK, NEW JERSEY.

nno'rnr. SYRINGE.

Application filed June 6,

To all whom, may concern Be it known that I, RioHAnn PALMER, a citizenof the United States, residing at Teaneck, in the county of Bergen andState of New Jersey, have invented certain new and useful. Improvementsin Rectal Syringes, of which the following is a specification.

The present invention relates to improvements in rectal syringes, andparticularly such syringes of the type in which the noz zle rests upon arecumbent bag, the weight of the person using the same, causing thewater to flow from the bag through the nozzle.

An object of the invention is to provide an improved syringe of thischaracter wherein means will be provided which will permit othersubstances, such as medicinal tablets. oils or the like to be mixed withthe liquid passing from the bag to the nozzle, without allowing suchsubstances to come into con tact with the rubber bag. A further objectis to provide means by which the flow of liquid may be regulated orentirely stopped as desired.

As these advantages are also desirable in a syringe of the fountain typewherein the bag is suspended at a height and the flow of water dependsupon the force of gravity, I propose to provide means whereby myimproved syringe may be convertible into this suspended type, commonlycalled the fountainsyringe. It is a still further object to provide animproved form of bag which may be used with more comfort and convenienceand controlled with greater case than the previous types of such bags inuse.

Vl ith these and other objects in view my invention is shown in theaccompanying drawings and will be hereinafter more fully describerhwithreference thereto, and finally pointed out in the claims.

Fig. 5 is a side view showing my invention used as a fountain syringe.

F1g. 6 is a similar view showing a slightly differentmanner of using'thenozzle. I Similar reference characters indicate corresponding partsthroughout the several. fie} ures of the drawings. Referring to thedrawings, and more pa rticularly to Fig. 1 theredf, my inventioncomprises a bag 10, formed in the usual manner of rubber, and providedat one end with neck and funnel l1 fitted with a stop per 12, and a tab18, having an eyelet 14 therein for hanging the same up when not 111 useor when used as a fountain syringe, as hereinafter more fully described.The other end of the bag is contracted as at 15. being of less width andthickness than the main body portion of the bag, and giving to the basomewhat the appearance of a bicycle saddle. I I

A box or receptacle .16 is connected to the contracted end 15 of thebag, by means of a bushing 17 from which the receptacle may be readilydetached when desired for purposes of cleaning, by means of the screwthreads 18. A. valve 19 for controlling the flow of water from the baginto the receptacle is provided in the bushing 17, the handle 20 ofwhich is elongated, and. extends forwardly of the receptacle where itmay be manipulated with ease by the person using the syringe. A checkvalve 21 is provided onthe upper end of the bushing which permits theflow of water under pressure into the receptacle, but prevents thereturn of the water in the receptacle to the bag, so that the same isfree from any deteriorating effect the mixture in the receptacle mighthave on the rubber.

.A rap 22 is provided on the upper side of the receptacle and is screwthreaded thereon to make a water tight connection, and at the side thereare provided bushings 23 and 9A, the ends of which project into and outside of the receptacle and are screw threaded,

A closure cap 25 is screwed onto the exterior end of the bush ng 23, anda tube 26 is screwed onto the exterior end of the bush ing 24;, whichtube may be either flexible or still as desired. At the outer end of thetube 26, the base piece 27 of the nozzle 28 is secured, the base beingof sufficient width to rest in upright position on the bag .10 withoutbeing otherwise secured. It will be noted that the nozzle 28 isdetachable from -moving therethrough the medicinal subthe base piece,being screwed thereon, the screw threaded projection 29 of the basebeing of a corresponding size to the threaded ends of the bushings 23and 2a.

A sack 30 of wire netting or the like is suspended within the receptaclebeing provided with hooked portions 31, which engage the annular flange32 at the month of the receptacle. This sack 30 is adapted to containmedicinal tablets, or other suitable substances, it is desired tocombine with the liquidv in the bag.

In operation, the liquid in the bag under pressure caused by the weightof the person using the same, is forced through the bushing 17 the valve19 of which is first opened, and the check valve is opened so that the'Water enters the receptacle 16 combining with the substance containedtherein and in this combined state passes through the tube 26 and outofthe nozzle 28. As the liquid passing through the receptacle iscontinually stance combines gradually with all the hquid in the bag,resultm in a uniform mixture,

l/Vhenit isdesired to use another liquid, such as oil, with the liquidcontained in the bag, the sack 30 is removed from the receptacle and anattachment shown in Figs. 3 and 4 is placed therein. This attachmentconsists of an upright tubular member 33 closed at thetop and adapted tobe engaged snugly over the cage of the check valve 21, and against'theupper side of the bushing 17. Laterally extending tubular portions 3dand 35 are provided at the upper end of the tubular member 33, which areconnected at their outer ends to the inner threaded portions ofthebushings 23 and 24 respectively, by means of interiorly threadedslidable sleeves 36 and 37. Openings 38 are provided in the tubularmember 33, through which the liquid in the receptacle is gradually drawnby the passage of the liquid from the bag and carried therewith. In theslightly modified construct-ion shown in Fig. 4, a number of tubularextensions 39 are provided on the tubular member 33 which extendapproximately to the bottom of the receptacle. By placing a clamp on thetube 26 orhaving a valve therein which may be closed before use of thesyringe, the liquid is prevented from entering the tubular member 33.Vhen the valve is opened and the liquid passes out of the bag 10 asiphoning effect is produced which causes the liquid in the receptacleto be gradually and uniformly mixed with said liquid passing from thebag.

When it is desired to use the invention as a fountain syringe, the bag10 is suspended at a height by means of the tab 13 as indicatedin Fig.5, the cap 25 is removed from the bushing 23 and placed upon the bushing24 from which the tube 26 is removed, or if desired the receptacle maybe merely turned, a half turn on the bushing 17 which will bring it intothe correct position. A tube 41:0 is screwed to the bushing 23, or 2i,ii the receptacle is turned. and the tube in and nozzle are secured tothe end of the tube.

If desired the nozzle 28 may be removed from the base and placed uponthe end ol the tube. It is unnecessary in this case to remove the tube26 from the receptacle, the opening of the same being closed by screwingthe cap 25 on the threaded projection 2E) of the base.

My improved invention is simple and eifectual in use, and all of theparts may be kept in a thoroughly sanitary condition, which is highlyessential in a. device of this character. The form of the bag will proveespecially desirable, permitting the same to be used in a natural andcomfortable position, and enabling a convenient and positive control oithe flow of liquid.

I have illustrated. and described a pre ferred and satisfactory 'lorinot iny invcntion, but it is obvious that changes may be made thereinwithin the spirit and scope thereof, as defined in the appended claims.

I claim:

1. A bag comprising a body portion adapted to contain a liquid andhaving a central sustaining part, said body portion provided with afilling neck extending from one part thereof and a projecting portion atanother part adapted to fit between the legs, and a nozzle incommunication with the pro jecting portion and adapted to rest upon theentral sustaining portion of the bag body.
